Xcode 8 iOS 10 UITableView Problem: UIImageView added from storyboard is displayed until the table scrolls

Question

I have table views in my storyboard, and it works until Xcode 7.3, after upgrading Xcode to 8, the images that are added to tableviewcell don't appear for the first time until you scroll OR explicitly call reloadData. Images are viewed from the storyboard.

After scrolling

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
ALContactCell *contactCell;

switch (indexPath.section)
{
    case 0:
    {
        //Cell for group button....
        contactCell = (ALContactCell *)[tableView dequeueReusableCellWithIdentifier:@"groupCell"];

        //Add group button.....
        UIButton *newBtn = (UIButton*)[contactCell viewWithTag:101];
        [newBtn addTarget:self action:@selector(createGroup:) forControlEvents:UIControlEventTouchUpInside];
        newBtn.userInteractionEnabled = YES;

    }break;

    case 1:
    {
        //Add rest of messageList
        contactCell = (ALContactCell *)[tableView dequeueReusableCellWithIdentifier:@"ContactCell"];

        [contactCell.mUserNameLabel setFont:[UIFont fontWithName:[ALApplozicSettings getFontFace] size:USER_NAME_LABEL_SIZE]];
        [contactCell.mMessageLabel setFont:[UIFont fontWithName:[ALApplozicSettings getFontFace] size:MESSAGE_LABEL_SIZE]];
        [contactCell.mTimeLabel setFont:[UIFont fontWithName:[ALApplozicSettings getFontFace] size:TIME_LABEL_SIZE]];
        [contactCell.imageNameLabel setFont:[UIFont fontWithName:[ALApplozicSettings getFontFace] size:IMAGE_NAME_LABEL_SIZE]];

        contactCell.unreadCountLabel.backgroundColor = [ALApplozicSettings getUnreadCountLabelBGColor];
        contactCell.unreadCountLabel.layer.cornerRadius = contactCell.unreadCountLabel.frame.size.width/2;

After lengthy bumps and tests, it worked after the upgrade.

dispatch_async(dispatch_get_main_queue(), ^{
 contactCell.mUserImageView.layer.cornerRadius = contactCell.mUserImageView.frame.size.width/2;
 contactCell.mUserImageView.layer.masksToBounds = YES; 
});
